Quite a few of my contacts have recently asked me to describe the steps I take to create one of my hand-stitched, double-image vertoramas.

So I’ve typed up this little tutorial...

Motivation: My main motivation for creating my vertoramas is to show more of the scene than can be captured with only one frame.

The next most important reason is that with a vertorama, I can correctly expose for the sky and for the foreground. Unless I use a (carefully aligned) graduated neutral density filter over my lens when shooting a landscape scene, no matter how much I fiddle with my camera’s settings, I’m either going to get an underexposed foreground, or an overexposed sky!

I could of course process my images using Photomatix, but that’s another discussion that I don’t wish to enter into now. Other than HDR, there is simply no other way (that I know of) to achieve a balanced exposure throughout the entire image.

Software: To process my vertoramas, I use Paint Shop Pro (version 11) and a collection of plug-in filters called nik Color Efex Pro 2.0 - Traditional. Although I’ve used Paint Shop Pro to process my photographs, there is absolutely no reason why my tutorial won’t work for Photoshop, or any other photo editing software that supports layers and third-party plug-in filters.

I now no longer use any panorama stitching software to align and stitch my images, since I firmly believe that I can do a better job by hand! I’m not saying that I’m perfect however... and I’ll happily review my opinion as soon as someone can show me any stitching software that is able to recognise the objects that it is stitching (and treat them accordingly (like keeping the horizon straight)).

Preparation: Before I take the photographs for any vertorama, I first decide where the best place to stitch and blend the two images will be. This is easy when I have a clear horizon with cloudy skies, but a little more tricky when the scene includes objects that span vertically across both images. Since I’m mostly shooting with my 11mm ultra-wide lens these days, there is usually lots of perspective distortion at the edges of the frame. I always look out for that, and try to minimize any distortion where possible.

These days I also always shoot at least 20 to 30 images for each vertorama. I do this at slightly varying apertures and shutter speeds, and with small adjustments in viewing angle. With the ultra-wide lens, I’m constantly amazed how moving the lens a degree or two in any direction can present a completely different perspective. Although there are often only minor differences between any of the images when I sort through them later, there are usually one or two images that clearly stand out as being better than the rest. Besides a quest to capture the perfect photograph for any scene, my main reason for shooting off so many different shots is that... it usually costs me some time and effort to get into the position where I’m ready to take the photograph, but it doesn’t cost me anything extra to take a few dozen more shots!!

Stitching and Blending: Okay, after selecting the sharpest, best exposed, and most interesting two photographs, the next step is to seamlessly blend them together into one image. The first part of this step is to get the two images to match as closely as possible in terms of perspective distortion and exposure. It’s usually very easy to blend two images somewhere in the cloudy sky, especially if there is very little difference in their exposure... so that’s why I’ve selected the following two images for this tutorial. This is what they look like before I start any processing (straight out of the camera)…

First I create a new canvas that is a little bit larger (both vertically and horizontally) than the two images stacked together, and then I open each of my original images, copy them to the clipboard, and paste them as new layers onto my new canvas. I usually paste the sky layer first and after pasting that layer, I move it up to the top of the canvas. When I’ve pasted the ground layer on top of the sky layer, I set the layer transparency to about 50% (so that I can see through it) and then drag that layer down to fit together with the sky layer as closely as possible. When I’ve moved the layers into position, I reset the upper layer’s opacity back to 100%.

Sometimes I need to do some perspective correction, rotation and resizing to get the layers to fit perfectly, but sometimes (like this time) it’s not really that important to get an exact fit... blending clouds can be very forgiving!

Having moved and adjusted the two layers until they match as closely as possible, the next step is to rearrange the order of the layers and to remove either the ground portion from the sky layer, or the sky portion from the ground layer. In this example, I’ve placed the ground layer above the sky layer (in the layer palette order), and I’ve blended its sky together with the lower layer’s sky.

I realise that all this sky/ground, upper/lower, layers business might sound confusing to some, but I’m confident that this will make perfect sense to most people familiar with working with layers. When I refer to sky and ground layers, I am always referring to the top and bottom parts of the vertorama, and when I refer to the upper and lower layer, I am always referring to their order in the layer palette.

But before I attempt to blend the layers together, I must first attempt to get the exposures in the blending area to match as closely as possible. Blending two layers with perfectly matching exposures is often as simple as dragging a soft eraser brush over the hard edge of the upper layer. But the task is usually a little more difficult when the exposure of the area that you want to blend doesn’t quite match.

In this example, the exposures did not match perfectly, so I had to lighten the sky layer a little and then apply nik’s amazing Graduated Neutral Density plug-in filter to the ground layer. I’ll explain how I apply these filters in the next part of this tutorial, but for now I’ve got to say that this filter has got to be the most useful plug-in filter around... it gradually either darkens or lightens either the top or the bottom part of any layer (with all degrees of control). In this tutorial, I slightly darkened the sky part of the ground layer, until the exposure of the two layers matched perfectly.

So having tweaked the exposures to match as close as possible, the next step is to blend the two layers together, so that not even a trained eye (at the highest magnification) would be able to find the stitch. This is where practice makes perfect... your first blend might not be seamless, but I can promise you that you will soon surprise yourself with how easy this actually is!!

To blend the images I always use the eraser brush tool, with a range of sizes, transparencies and hardness. I start off by setting a very soft-edged brush, and completely erasing (no transparency) the line that defines the join between upper and lower images. Then I increase the brush transparency and continue to brush away the part of the image in the upper layer where I want image in the bottom layer to shine through. Some parts of the image often require small hard brushes, while other parts might only need a large soft brush for a seamless blend.

Sometimes the sky and ground layers have such widely differing exposures (like when shooting directly into the sun) that it is impossible to blend the skies of the two layers together. In these cases, I usually select (with the magic wand tool) and remove the entire sky part of the ground layer, and then I use a very small brush at high magnification (zoom) to carefully erase all remaining traces of sky from the edge of the horizon.

Each vertorama will present you with a new challenge and will require slightly different blending techniques. But the feeling of satisfaction that you will experience when a blend is flawless, is always worth the time and effort that you’ve put into it (in my opinion)!

Although not flawless (at high magnifications), my blended vertorama now looks something like this...

Processing Tricks: Now that I’ve blended the two images to my satisfaction, I merge all the layers into one layer. Then I duplicate it and turn off the visibility switch of the original layer (to preserve a copy of the image before I started messing around with it). From now on, I will make each adjustment on a duplicate copy of the original layer, finally merging all layers into one when I’ve made all my adjustments and when I’m happy with the way that each adjustment has affected all the others.

Rather than trying to get the exact look that I’m after with only one or two plug-in filters, I’ve discovered that applying tiny little bits of many different filters and effects, achieves a much more realistic (and pleasing) end result. Instead of applying an effect directly to a layer, I will always apply the effect to a duplicate copy of the layer, and then adjust the transparency of the effected layer until I can only just make out the difference between the original and the effected layer (by toggling the effected layer’s visibility switch). Then I merge the (mostly transparent) effected layer with the original untouched layer.

One of the things that I always take great care in avoiding while processing my images is applying some effect that discards any of the image’s details. I’m very, very careful not to do anything that burns out any of the original highlights, or further darkens the shadowed areas!

Although I usually process each image slightly differently to all the others (as the situation requires), over the past few months I’ve discovered that the following effects and filters give me exactly the kind of look that I’m trying to achieve...

Firstly, I adjust the Highlights, Mid-tones, and Shadows to try to reveal any hidden detail and to try to balance the tones.

Next, I may (or may not) use nik’s Graduated Neutral Density filter again, to darken the sky a little more, or to lighten or darken the foreground a little.

Then, I’ll always use a little bit of nik’s Sunshine filter, which although difficult to describe in words, can transform and breath light into even the dullest of images.

Then, to add a little bit more warmth (when required), I’ll often use a miniscule amount of nik’s Skylight filter (this one can really bring out all the gorgeous sunset colours).

Then, I might also add a bit more brilliance to the primary colours by applying a little bit of nik’s Brilliance and Warmth filter... not too much, because this one can really destroy all your highlights!

When you view a merged layer of all the effects that you’ve applied so far, you’re going to be in for a shock... it’s made everything too dark, and completely over-saturated!! This is when I use nik’s Contrast Only filter, which despite its name, will allow you to adjust the brightness, contrast AND saturation. I always decrease the saturation, and I usually increase both the brightness and contrast using this filter.

Next, I apply some (soft light) high-pass sharpening with the radius set to between 4 and 6 with 60% strength. This is another stage of my processing workflow where I’m always extremely careful not to destroy any image data by over-sharpening and introducing haloes.

Finally, I use nik’s Lighten/Darken Center filter to ever-so-slightly lighten the center and darken the edges. This subtle vignette effect helps to give any image a sense of depth, and can often make the world of difference to an otherwise flat image!

So, having applied all my image adjustments, the vertorama in my tutorial now looks like this...

Okay, now I’ve just spent one entire evening sharing all of my image-processing secrets with everyone... Why did I do that? Well, if there is only one person who feels inspired enough to try what they’ve read here today, then I feel that it will have been worth every minute that I’ve spent typing this!!

It was you who inspired me to try my hand at this "vertorama" method and your lessons from about two months ago certainly peaked my curiosity to try this method. I took up the challenge and never looked back. Thank you.

Thanks for this great tutorial Paul. I guess I know why I have failed so far. I am just trying to stitch images that are too complex and with too much lens distortion! I'll soon go back in the field and try something simple first, and will be honored to post in in the pool!

Very kind of you to take time out and discuss your technique Paul!Ever since your striking images caught my eye, I have been considering doing some Vertorama's, I'll post my results in the group once I have!There are a couple of variations to your technique that I have in mind, I'll happily share them once I've tried them out!The only thing you didn't mention was camera support, do you use a specific tripod head? I've got a manfrotto 303 plus, which I have been using to do horizontal panos for years, I'm guessing it is just a case of changing the axis of rotation to minimize the parallax error caused by lens distortion, I will hopefully be finding out soon! ☺

Many thanks Paul. This is great and I can't wait to try it out. I must however admit that a lot of what you have described has gone right over my head. I would definitely have to first improve on my very basic understanding of Photoshop, layers and related techniques. To date, I have very much used automated stiching techniques - nothing like what you have described here. I can however clearly see why you are doing it this way, as your techniques address the exact problems that I am experiencing with the automated process. I also now understand why your photos look so great. Well done and many thanks for making the effort to write it down for us. Thanks also for the invite to your group. I am looking forward to contributing on a regular basis. Regards.

Although I also use a Manfrotto panoramic head on my tripod when I shoot my multi-image horizontal panoramas, I've found that it is not so important to keep the camera perfectly steady between shots when I'm going to hand-stitch them as a vertorama!

While stitching software combines the images by adjusting the perspectives and then overlapping the images... whatever you see in a hand-stitched vertorama either belongs in one image or in the other... and is seldom a combination of both images overlayed and merged together! So, although this technique is not as quick and easy as using software like Autostitch or Panorama Factory (my personal favourite), parallax errors are (fortunately) non-existant when I hand-stitch my images.

Wow, Paul, I'm overwhelmed - sounds like lots of work but it's really great - seem the only way to the perfect photo? Yes a tripod is very important (which I have ;-) )Fantastic work and thank you for sharing your knowledge. I think in your technique you are ancompared anyway :-)

Thanks so much for taking the time to write all this down!! Wow, I can see that my wide angle has so much potential. I have admired Andre's shots for a while and yours are fantastic too. Again thanks so much for sharing this. I look forward "trying"

Gee Paul, I managed to find a link to this and usually if something is more than ten words I skip it, however not this time! This is a brilliant tutorial and I will DEFINATELY try your tricks and secrets!!! :o)

Thanks very much for sharing your expertise with us! I'm sure everyone who reads this will be inspired! and ready to give it a try!

I want to thank you for the time you took to write such a clear tutorial. I am inspired to try this myself. I've done many horizontal panoramas, and only a few m x n panoramas. But this straightfoward 1 x n vertoramas looks like a great idea.

Well i was waiting for it. Thanks for spending your precious time. This tutorial is really precious.

Thank you so much Paul, i read this just as i felt inspired to create some vertoramas after looking at your pictures. I felt hand-stitching my images are a lot better too(photoshop kinda messes it up)... i read this after creating two of my (better) vertoramas and cant wait to try this out. I never shot with this technique in mind, so i guess il go do some shooting too. I just want you to know that I and all the others here appreciate your effort to share this with us. You are a real inspiration!

I just noticed that over a year ago Daniel was the 2nd post on this thread... if he used your tutorial to acheive the level of excellence at which he now operates... then you should be very satisfied that you spent an evening saring you secrets... Thank you very much!

Nazar linked me to this beautifully composed Tutorial.. and I learned a lot from it.... I was always amazed by looking into vertoramas.. and now I think I have some idea to create some of my own... Thanks Paul.... Its was very nice knowing you.

This is a great tutorial Paul, thanks for taking the time for writting this! like a lot of people in this thread, I feel inspired by this new technique (meaning new to me!), so I look forward to spending time fighting with PS if the results are only a fraction of what I see in your photostream! Once again, many thanks for sharing this with all of us!

I think I've got a long way to go to fully get this down, but I appreciate the tutorial and find vertoramas fun and challenging. Thanks so much for putting this tutorial together, and hopefully I'll have some images in a year or two as nice as yours. :-)

What a fantastic tutorial , I read it early this morning, checked out a few more of your images then while out and about got the chance to try some shots to see if I could do it, most impressed indeed and a instant fan of your style of Vertoramas so thanks heaps

Thanks for sharing your tips and tricks with all of us Paul. I found this very interesting, and I'd like to have a go myself. There's a lot to take in, but it'll be fun trying to get to the end result.

Thankyou Paul for taking the time to prepare this. Are you using a panoramic head at the time of exposure?

Thanks for taking the time to explain the process. I would say that using layer masks and a black or white paint brush is bar far the easier and more controllable method of blending images. I often hand blend up to 5 images to get a decent exposure, which I find better than hdr. It involves linking a layer mask to each of the layers and then altering the opacity of a paint brush to seamlessly blend away one image. It would also work really well for the vertorama I think. Anyway, a nice tutorial none the less. A Ts-e lens would be able to give you two images without any distortion between them :)

i would love to thank dr.panorama paul for introducing me to your vertoramism! u were right.. with using vertorama we can use correct exposure for each foreground and sky! and im really addicted to verto everytime i switch on my camera..

Great tutorial! I have never tried a vertorama, until recently I hadn't even heard of it!! You have laid out the process in such clear terms, it's sparked my imagination and has made me want to try for myself!

Thanks for taking the time and effort to share with those who have less experience. It's people like yourself that make Flickr such a great place.

Thanks for this fantastic tutorial Paul...can't wait to give it a try.

I noticed in your instructions that you use the eraser tool...it is my understanding that even though you work on a separate layer...is this not a destructive process...would layer masks do the same and not be destructive and are layer masks ok as part of the criteria for acceptable posting of vertoramas...Glad to see that someone else uses high pass sharpening with soft light...works so well for so many images.

Great tutorial, I have been doing these for a bit now and never even knew what they were called. I also have the nik filters but have never tried the ones you describe, I will soon. Thanks again and keep up the good work.

Just reviewed the editorial Paul and found it to be very interesting and useful. Thank you for the post, you have inspired me to continue pursuing the perfect vertorama - just in time as we have a photo shoot weekend at lake Huron in two weeks. Thanks again! Warren

Even more respect for you Paul after I've read the above tutorial. It's an amazing huge work your putting in it. Don't know if I'm going to try this and for now I'm a "beginner" but this is very challenging and maybe in the future.... Very kind of you to share all of this information. Thank you!

Amazing tutorial!! I'm still new to photography and I can wait to try this out. One quick question for anyone willing to help out: would you recommend using two already done HDR photos before combining?...or that a needless step?
